Retro FPS Kit is a game template inspired by classic first-person shooters like Wolfenstein and Doom.
This package provides everything you need to kickstart and expand your own retro-style FPS project – without writing a single line of code. Both weapons and enemies are represented with fully animated 2D sprites, while enemy characters feature 8-directional animations for authentic retro movement.
Why choose this kit? Because it allows you to build a fully playable FPS game in minutes. All systems work out of the box and can be configured directly through the Unity Inspector – no programming required.
